A freelance Oracle PL/SQL Developer performs a variety of design and software implementation duties on a contract basis. Your responsibilities include communicating and collaborating closely with other developers and project managers to assess a client's goals and needs for a specific application or tool. You then develop and program the software, design the database structure using the PL/SQL programming language, and implement the use of the application for your client. As an independent Oracle PL/SQL developer, you may also use other languages, such as Python, Java, and PHP.
